GSL Twin System

Our twin 4" stainless exhaust system is our most popular exhaust by far for the 79 series LandCruiser crowd.

It is what we like to call the full GSL treatment because it produces the sound we’ve worked so hard to achieve. Plus, it’s the sexiest system we offer by far; twin, brushed stainless steel and 4 inch pipe? Yes please!

Adventure proof twins

Adventure proof

If you plan on getting a cruiser, chances are you plan on giving it a bit of a hammering, whether it be off-roading, camping, beach driving, Hill climbing or more. We’re exactly the same, and because of this, we strive to make sure our exhausts are built to withstand the toughest adventures. High quality 304 grade 4’’ stainless steel, sturdy custom folded bracketry, and top quality welding work.

TURBO BACK (DPF DELETE)

The ‘Turbo back’systems are great for pre DPF models (pre-2017).
They give the nicest note, and best performance gain of all exhaust types, however more recent models are legally required to have a DPF in place. This variant removes the DPF entirely and in most areas, is an illegal modification - thereby voiding any warranty’s on the vehicle.

This is an option recommended for offroad and track use only.

The system starts with a 5 inch dump, moving into a 4 inch CAT, a 4 inch muffler section, and splits off into two 4 inch tails.

ELITE DPF SYSTEM

Fully australian made High flow DPF (Deisel particulate filter). The main reason for this mod is to give you the V8 note that standard DPF models are lacking. Being a high flow, this eliminates the bottlenecking issue with the standard DPF’s, and assures consistent power with no drawbacks.

This option is great for everyday use, keeping your vehicle compliant with vehicle emission standard.

DPF BACK

This system utilises the standard DPF, while still delivering the great note of our exhausts. If you’re chasing sound over performance, then this is the perfect exhaust. From the back it’ll look just as good, so you don’t miss out on aesthetics either!

This option is great for everyday use, as it’s a little quieter and keeps your vehicle complient with vehicle emission standards.

The system starts with a DPF to 4 inch adapter section, moving into a 4 inch CAT, a 4 inch muffler section, and splits off into two 4 inch tails.
